Ran Postar commented on HIVE-1643:
----------------------------------
I understand that pushing down the expression to hbase is complicated
especially when working with multiple tables. But is it possible to add a
hinting mechanism?
We can added to each "from table" a hint for startRow and stopRow for the scan,
and when HiveHBaseTableInputFormat scan the table it will added the startRow &
stopRow. And for the first Part we will leave the user the possibility to
optimize specific table scan.
> support range scans and non-key columns in HBase filter pushdown

> HIVE-1226 added support for WHERE rowkey=3. We would like to support WHERE
> rowkey BETWEEN 10 and 20, as well as predicates on non-rowkeys (plus
> conjunctions etc). Non-rowkey conditions can't be used to filter out entire
> ranges, but they can be used to push the per-row filter processing as far
> down as possible.
